Taall whom. t 'may conca/vz.:

AvBe v.itlrnown that I, `MARCELLA BEVERLY, a citizen of the United States, `residing at 5019 Lindsley Ave.,Dallas, inthe county of Dallas and; State ofTeXas, have invented certain new and'nseful Improvements in Flour Sifters and Lighteners, of which thel following is a specication.

This inventionrelates to sifters, and Aespecially an improved flour ysifter and lightener.

The main object of this invention is -to generally improve on devices of this character. l

Other objects and desirable features will be pointed out or implied in the following details of description, in connection with the accompanying drawings in which Fig. 1 is a top plan view of my improved device: Fig. 2 is a vertical sectional view through the center of the device; and Fig. 3 is a detail view of a portion of one of the rings that carry the cross-bars or beaters that lighten the flour.

The invention consists in the construction and arrangement or combination of parts which will now be fully described in connection with the accompanying drawings in which similar reference characters correspond to similar parts throughout the severalA views A hollow cylindrical open-ended body or shell 5 is provided with annular beads 6 whose inner surfaces form annular tracks or guides in which are seated rings 7 which are movable circumferentially, but not movable axially. Each of these rings 7 is united with a pair of cross-bars or crossed bars whose centers are apertured at 9, and these centers register with one another at the center of the respective rings 7 and of the cylinder 5.

A wire or rod 10 is bent at` opposite ends of its middle portion which form's a handle 11, and from this handle it extends to the center of the cylinder where it is bent and extends axially towards the bottom of the cylinder, and its end portions 12 are thus axially alined and pass through the respective pairs of openings 9 at their centers andare there secured by solder or any appropriate means. These portions 12 also pass through central openings in two other pairs of crossed bars 13 which may be properly called sifting members, being movable .on 9.1" immediately aber@ screens `le of Wiremesh.l 4a The-upper one ,of .these .screens isgsecured to: the V,inner surface of the "cylinder .or shell 5. iby` anyv appropriate. means; butthe lower one ;is .preferably 1.secured."..y to a. lrremovablef sheet-,metal ring..1b.rwhicl1. is. frictionally orvotherwisei held'. inv .theagshell 5 and f provided f with.l van annu-larachannel .'16 which receives Athe .lower `edgeiothe'cshell 5 so` .as to, '-stifl'en the bottom.` of the..device and. prevent. fthe: screen. from.:bearing-. .too hard against the lower sifter-bars `13,these latter being secured to the lower part 12 by any appropriate means. The outer flange of the channel 16 also` serves as: a hand-hold by means of which the ring 15 can be withdrawn from the shell 5 for removing any lumps or foreign matter that might have gotten through the upper screen. It should be understood that one or more other removable screens may be added under these screens, or that fixed screens may be added with the provision of a door or doors in the shell for removal of the lumps and foreign matter; also, that additional beaters and sifter-members may be added for the additional screens, and these may be secured to or attached to the member 10 in any appropriate way.

The member 10 extends through slots 17 of the shell 5, also through openings 18 of covers or strips 19 which are slidable through openings .between the wall of the member 5 and an upper and lower strap` or guide 20. The strips 19 cover the slots 17 and preventthe waste of iour therethrough. A supporting handle 21 is provided and secured on the opposite side of the shell 5 from the operating handle 11, and when the devicey is supported or held in place by the handle 21, the handlell can be oscillated for oscillating the several sets or pairs of crossed bars, and duringthis operation the member 10 moves along the slots 17, and the members 19 move behind the guides 20. If flour is in the device when thus operated, it will be beaten or stirred and thus caused to pass through the screens 14 and thus become ire-.Aram i sifted, and lightened in regard to its'mass.

be made within thescope of the inventive idea as implied and claimed.

What I claim as my invention is 1. In a sifter, the combination of a cylin- .decal Shell levies annular grOOY- Q1" track in its wall, a ring seated in the groove for circumferentialk lmovement' and Vheld f against axial movement, a bar or beater sev drical shell provided with upper and lower annular tracks, upper and lower beaters provided with guiding means mounted to travel along said tracks, an upper screen under the upper beater, al lower screen under the lower beater, a` sitter-member between the upperbeater and upper screen, a siftermember between the lower beater and the lower screen,lsaid shell being provided with a slot above the upper screen and a slotbel tween the upper and lower screens, and an operating handle provided with elements extending inward through these slots and having traveling movement in the slots, the inner ends ofthe said elements being secured to said beaters and said sitter-members, sub-v stantially as shown.

3. lIhe structure defined by claim 2, the i lower screen being provided withV supporting `means which includes av ring whoseupper part is vfitted removably in the: lower end of the shell, the lowerl end of said ringl being provided with a channel which receives the lower end of the shell and -also '1 provides a vhand-hold, :substantially a shown, for the purposes speciiied. i

In testimony whereof I aiCiX my Signature.

MARCELLA.` BEVERLY.
